Set the discharge pressure of your air compressor to between 70 and 90psi. The higher the pressure, the greater the vacuum your pump will draw. At 90psi, I obtained a vacuum of around 24″ of mercury (inHg), equivalent to 11.79psi or 0.8 atmospheres. That's a lot. Fun with a vacuum pump. What will you do with your vacuum pump? Science!

How Does Pump Suction Limit the Flow? | Pumps & Systems

Dec 17, 2011 · One of the advantages of centrifugal pumps over positive displacement pumps is an ability to operate with a wide flow range. Since a centrifugal pump operates at the intersection of a pump curve and a system curve, varying the system curve easily changes the pump's operating point (see Figure 1). Figure 1. Flow control of the centrifugal pump by the discharge valve

A vacuum pump is just an air pump that you use for sucking rather than blowing. You can convert an old-fashioned "floor pump" ("bike pump") into a vacuum pump that can take over 75 percent of the air out of something. That's several times as strong as a vacuum cleaner's pull, and three quarters as strong as the best possible vacuum pump.

Vacuum Pumps: Why use them & what do they do?

Vacuum Pumps: Why use them & what do they do?

A vacuum pump has the inlet hooked up to one or both valve covers, sometimes the valley pan. It SUCKS the air from the engine, thus reducing the air pressure build up created by blow due to combustion gases going past the piston rings into the pan. Vacuum pumps vary in the amount of air volume (CFM) they can suck so the potential VACUUM a pump .

HOW TO design a pump system

HOW TO design a pump system

The pump produces pressure and the difference in pressure across the pump is the amount of pressure energy available to the system. If the fluid is dense, such as a salt solution for example, more pressure will be produced at the pump discharge than if the fluid were pure water.
